Riley Liddell, MS, L/CPO, Licensed and Certified Prosthetist Orthotist, Director of Orthotics and Prosthetics | Lower Extremity O&P Specialist
Riley Liddell earned a Bachelor of Science in Kinesiology with a concentration in Human Movement Studies in 2013. With a background in strength and conditioning, he initially pursued physical therapy before shadowing at a Pacific Medical clinic during his sophomore year and changing his career direction to orthotics and prosthetics. He earned his Master of Science in Orthotics and Prosthetics from California State University, Dominguez Hills in 2016 and completed two years of orthotic and prosthetic residency training with a large national provider in Olympia, Washington.
Riley joined Pacific Medical in 2018 as Practice Manager for the Corvallis and Salem, Oregon clinics and was promoted in 2020 to Director of Orthotics and Prosthetics, overseeing the company’s O&P division. He also serves as Pacific Medical’s lower-extremity O&P specialist, providing consultation and clinical support for complex cases across the company’s clinics.
Riley has extensive training, certification, and experience in lower-extremity prosthetics, advanced socket solutions, and microprocessor knee and ankle/foot technologies. He has a strong interest in emerging technology, including 3D design and printing, and believes in exploring new treatment approaches when they can provide an evidence-based, best-practice outcome. His experience has also extended into advanced upper-extremity prosthetics, including integrating Coapt pattern recognition with an Ottobock AxonBus powered prosthetic system.
Riley’s clinical philosophy emphasizes evidence-based practice, objective outcome measures, and treating the patient as a whole. He has worked with multiple hospital systems to develop standardized multidisciplinary pre and postoperative amputation protocols designed to improve continuity of care for patients dealing with limb loss. He also works closely with O&P compliance and reimbursement standards to help ensure clinical practices align with current requirements.
Riley is an NCOPE Residency Director, has served on the board of the California Orthotic and Prosthetic Association, and volunteered for many years with the Challenged Athletes Foundation. He also participated in the 2021 OHSU Invent-a-thon, where his team’s Comfort Socket project earned first place and received grant funding for further development.
Outside of the clinic, Riley enjoys spending time with his wife and son and exploring the outdoors. His interests include bowhunting, golf, gardening and farm-to-table cooking, restoring and modifying vehicles, and woodworking.

The constantly evolving nature of O&P continues to keep Melanie interested in the field.
